Exome panels are commercially available, they don’t need to be customised or designed. Exome Sequencing 1. Although individual rare variants are not reported for the comparator exome, using it only for comparison with the proband, the parent may request reporting of rare variants of genes known to be associated with adult disease for which medical action could alter outcome. EXOME SEQUENCING of a single individual:  For the PROBAND with a rare phenotype, when the constellation of clinical findings is not recognized as part of a known syndrome, exome sequencing is the most cost-efficient and precise approach to diagnostic testing for rare inherited disease. Variants in the ACMG list of secondary findings genes are identified in approximately 1-4% of individuals (Kalia, et al., 2017, PMID 27854360; Olfson et al., 2015, PMID 26332594; Schwarz, et al., 2018, PMID 30100086).
